MACHINE FOR MAKING TUBULAR. Z BINDITIG.

Specification of Letters Patent.

AppIication filed 0etober 22, 1918. Serial No. 259,213.

To all whom it may concern:

Be it known that I, PAUL D. REDCAY, a citizen of the United States, anda resident of Royersford, county of Montgomery, State of Pennsylvania,have invented certain Improvements in Machines for Making TubularBinding, of which the following is a specification.

The object of my invention is to provide a machine for making tubularknitted fab-' rics which are used as binders and straps for underwear,and are made out of flat fabric folded and united at the edges andspooled so that when the binder is applied to the goods it is free oftwist and perfectly flat. I

In the accompanying drawings Figure 1, is a perspective view showingsufficient of the mechanism to illustrate my invention;

Fig. 2, is a front elevation of the spooling device and" Fig. 3, is anend view of the spooling device looking in the direction of the arrow,Fig. 2.

The numeral 1 indicates sufiicient of a sewihg machine head toillustrate my invention, having a presser foot 2 and needle 3 Thismachine is mounted on a suitable table 4; located in front of the sewingmachine and in line with the presser foot is a folder 5 through whichpasses the fabric a from a roll 6 mounted on any suitable spool. Thisfolder has a curved flat portion 7 around which the fabric a passes andhas a portion 8 which folds the fabric, as clearly shown in Fig. 1. Thetwo edges of the fabric are presented in line with the needle so that asthe material passes under the presser foot the needle makes theoverseaming stitch, fastening the two edges together, making a tubularstrip. T-his tubular strip is then wound in a flat condition on a spooland the spool is removed from the machine and located by the operator inanother machine for attaching the tubular fabric to underwear as abinding. single or double width as a shoulder strap for undergarments,if desired.

The spooling device is constructed as follows:-10 is a frame mounted onrollers 11 which are adapted to travel on a table 4. This frame has afixed upright 12 and a movable upright 13 hinged at let to the base ofthe frame 10. On the upright 13 is a spring The fabric can also be usedin acatch15 which engages a notched plate 16 on the base and this holdsthe upright 13 in a vertical position. spring catch from the plate 16,the upright 13 can be turned down on its pivot to allow for theremovalof the spool. The spool is mounted on the shaft 17 adapted to bearingsPatented July 27,1920.

On releasing the I 18 and 19 carried by'the uprights 12 and 13,

respectively- On one end of this shaft is a grooved wheel 20 aroundwhich passes a' belt 21 from a grooved wheel 22 arranged to slide on ashaft 23 adapted to bearings 24 secured to the under side of thetable 1. The'shaft has a spline 25 so that while the wheel 22 can slideon the shaft it can turn therewith. On one end of the shaft 22 is a Vgrooved driving pulley 26 around which passes a belt from any suitablesource of power. 2

:On theframelO is a bracket 27 which engages the wheel 22 as'shown inFig. 2. This bracket 27 extends through aslot'28 in the table. There isa slot 29 on each side of the slot 28 for the passage of the belt 21.The operator can move the frame 10 over the table so as to allow thefabric a to be Wound evenly on the spool 9. The spool 9 is detachablymounted on the shaft 17 and is driven by friction from the shaft. On theshaft is a friction disk 30, which bears against one end of the spool,and on the opposite side is a sleeve 31, and mounted between the sleeve31 and a fixed collar 32 on the shaft is a spiral spring 33, which tendsto keep the sleeve 31 against the end of the spool and presses the spoolwith snfiicient force against the friction disk to allow the frictiondisk to drive the spool and wind the material thereon as it is receivedfrom the folding and stitching mechanism.

34 is a handle which projects laterally from the frame and within easyreach of the operator. When it is desired to remove the spool, after ithas been filled, the movable upright 13 is released by pressing thecatch 15 and it falls so that the collar, sleeve and spring can bewithdrawn from the shaft 17-, after which the spool can be detached andanother spool placed in position.

By the above construction it will be seen that I amenabled to make atubular fabric foot of a sewing machine, and the needle mechanism makesan overseam stitch attaching the two edges of the folded materialtogether, forming a closed tube. This tubular fabric is then coiled Hat,with the seam at one edge, on the spool 9 and when the spool is filledit is removed from the machine and another spool is substituted for it.

I claim y j i 1. The combination in a machine for making tubular fabric,of a device for folding the fabric; a machine for uniting the edges ofthe fabric; a spool mounted to receive the fabric inaflat condition withthe stitching at one edge; means for driving the spool so as to take upthe-fabric as it is stitched; and means for causing the spool to travelin the direction of its axis and transversely to the direction of feedofthe fabric. 2O

ing atubula'r fabric, of a device for folding 2. The combination in amachine for makfor moving the frame in the direction of its axis andtransversely of the direction of feed 7 a of the fabric so as to allowthe fabric to be wound evenly on the spool.

3. The combination in a machine for making a tubular fabric with a seamat one edge, of a reciprocable frame; a shaft mounted on the frame; aspool carried by the shaft;

'- means for frictionally driving the spool from the shaft; a drivingshaft; a pulley arranged to move longitudinally on and turn with thedriving shaft; a belt passing around the pulley and around a pulley onthe driven shaft; and means for allowing the frame to be moved laterallyof the direction of travel of the fabric so that the fabric will bewound evenly on the spool. Y

4;. The combination of a table; means for folding and stitching afabric; a reciprocable frame; rollers supporting said frame on thetable; uprights on the frame; a shaft carried by said uprights, one ofsaid uprights being movable; a friction disk on the shaft; aspoolcarried'by the shaft and driven by thedisk; a spring mounted on'theshaft on the opposite side of the spool foryieldingly holding the spoolagainst the friction disk;

a pulley on the shaft; a splined driving shaft under the table; a pulleyslidably mounted on the said shaft; and means on the frame engaging thepulley so that when the frame ismoved the pulley will move with it.

In witness whereof I aifiii my signature. 7 7
